I'm trying to perform a low-level format of a new (32MB) hard disk drive. The problem is, I don't know the right address for the format. C800:5 is definitely not it. Unfortunately, I don't have the spec sheet for this disk controller, but the board says it's by ADAPTEC, INC (no address or phone number). It also says ASSY 401406-00 and Rev. E on the board. I've searched through memory in paragraph C800 and tried to find the right starting address, but it's like looking for a needle in a read-only haystack. I know that it contains a formatting routine because I've seen the text of several messages relating to it. In fact, I even got into the program once, but jumping to the same address again failed to have the same effect. When I did get it to sort of work, it asked several question that I didn't know the answer to, such as "step pulse rate", "number of logical units", and even the simple "number of heads" and "number of cylinders". The drive is a Miniscribe, and I assume the model number is HBA:15434 since that's about all it says on the label, other than "TN:1-13R". Well, can anyone offer any help with this mess? Has anyone even heard of ADAPTEC? If so, please send mail to GPOY@CORNELLA.CCS.CORNELL.EDU or GPOY@CORNELLA.BITNET (or, if you're lucky, {?}!cornell!vax5!gpoy). Sorry about the poor formatting of this article (no pun intended).

Depending on which controller you have, a 2002, 2010, or 2070 (the 2070 is RLL the 2002 and 2010 are MFM). For the ACB-2002A or ACB-2010A: Enter all numbers in HEX. Step pulse rate: 3 with jumper A-B installed (13 us) ECC correction span: should be 8 For the ACB-2070A: Enter all numbers in decimal: Step pulse rate: 3 (13 us) I hope this helps, I can't figure out which controller you have from my manuals as they only reference the 20xx numbers.
